STATEN ISLAND, N.Y. -- The Department of Motor Vehicles unveiled a powerful public awareness spot on drunken driving that will air on TV stations statewide beginning Monday.

The spot features the story of the Flynn family from Long Beach, L.I., whose 7-year-old daughter Katie was killed in a car wreck in 2005. After attending a wedding in which Katie was the flower girl, the Flynns were on their way home in a limousine when a drunken driver hit them head on.

"I was looking on the floor for Kate to make sure she was OK," her mother Jennifer explains in the video. "Her head had been torn from her body."

The spot ends with her father, Neil Flynn, asking the question: "Could you live with yourself if you murdered my daughter?"

The video is part of the "Drinking and Driving Shatters Lives" campaign sponsored by the governor's Traffic Safety Committee.

Martin Heidgen was convicted of two counts of murder in 2007 and sentenced to 18 years to life in prison.
